Build Interactive Web Apps with ASP.NET Core Blazor

Blazor is a framework for building interactive client-side web applications using C#, Razor, and HTML. It uses web technologies such as WebAssembly, SignalR, and Razor components to provide a modern web development experience. ASP.NET Core Blazor is the server-side version of Blazor, allowing developers to run the application logic on the server while still providing a fluid front-end user experience.

Getting Started

To get started with ASP.NET Core Blazor, follow these steps:

1. Install the latest version of Visual Studio.
2. Create a new ASP.NET Core Web Application project.
3. Select the Blazor Server template and choose “Create.”

Syntax

Blazor components are similar to HTML elements but are defined using Razor syntax. Razor uses the @ symbol for code that will be executed on the server and @: for code that will be rendered in the browser.

Here's an example of a simple Blazor component:

<h1>@Title</h1>

@code {
    private string Title = "Hello, World!";
}

Example

Here is an example of a Blazor component that displays a list of items and allows the user to add new items to the list:

<h2>My Shopping List</h2>

<ul>
    @foreach (var item in Items)
    {
        <li>@item</li>
    }
</ul>

<input type="text" @bind="NewItem" />
<button class="btn btn-primary" @onclick="AddItem">Add Item</button>

@code {
    private List<string> Items = new List<string> { "Milk", "Bread", "Eggs" };
    private string NewItem;

    private void AddItem()
    {
        Items.Add(NewItem);
        NewItem = "";
    }
}

Output

ASP.NET Core Blazor applications are rendered on the server and then sent to the client as HTML. Once the application is loaded, user interactions are handled by JavaScript using SignalR to send messages between the server and client.

Explanation

ASP.NET Core Blazor allows developers to write interactive web applications using C# and Razor syntax. Components are defined using Razor syntax and can be reused and composed to create complex UI elements.

Use

ASP.NET Core Blazor is a useful framework for building interactive web applications using C# and Razor syntax. It provides a modern development experience and is easy to learn for developers with experience using C# and Razor.
